nine SPINNING, LAND DOUBLING FRAME.

Application filed February I In the spinningand'doubling of yarns in aring frame it has been proposed to wind the roving oryarns coming fromthe delivery rollers around the tip of the spindle on which the yarnsare to be Wound in the form of a cop, the yarn coming from the spindletip and thence through a traveller or guide provided with a hook whichtraveller puts Winding tension upon the yarn in the ord nary manner of aspinning traveller. This has a certain disadvantage, as when the ringrail is lowered in the usual way to wind a few coils lower down thespindle before doffinga completed cop-to preserve continuity of the yarnand save piecing up for a fresh cop-the traveller hook or. the like isllable to catch .in the side of the wound cop and break. The provisionof special means of maintaining tension on the yarns during the descentof the ring rail, adds to the cost of the frame and requires extraattendance in operation.

It is the object to provide a combination of means wh ch will allow ofcontinuous and safe working of a spinning or doubling frame in which theyarn is spun or doubled at the spindle tip, thus obtaining theadvantages of such spindle spinning, by causing the yarns spun ordoubled to approach to the feel of yarns spun in thisway in the mule,and whlch means will allow of spinning on the bare spindle in a ringframe. This I effect by providing in combination, a spindle the t1p ofwhich is in the path of the material coming from the front deliveryrollers of a ring frame, and a winding guide in the place of the usualtraveller, which guide has its central portion which receives the yarn,absolutely straight, the yarn passing below the guide and thence to thespindle. There 1s thus no projecting portion onthe guide to fall overon' relief of yarn tension, and becomeentangled with the cop which hasbeen completed.

In illustrate the invention.

Figure 1 is a side elevation of the delivery rollers, with a spindle andring mounted in a ring rail; delivery rollers, ring rail, and means fordriving the spindle'are as usual; Figure 2 is a plan of a ringrailshowing a cop upon the spindleand the relation of the Winding thering rail.

'In'Figure 1, 4 are the usual 'delivery'rollers of a set of rollers uponthe usual roller stand 5. From the rollers 4 the roving descends to thetip of a spindle 6, the spindle being so arranged and of such a lengththat the'yarn 00 may be wound upon the tip of the spindle to be twistedthereon by slipping off the spindle tip, the twisted yarn then passingdownwardly underneath the guide 7 of bar form and thence to the spindle6 to be wound into a cop as usual-see Figures The ring is formed of twoparts, viz: the base 8 and the cover 9 shown in Figures 1 and 3which'cover is placed over the base as seen in the latter figure andgiven a slight turn to be secured in position by a bayonet joint 10Figure 1.

The guide 7 may be of steel and be slightly resilient and the tension ordrag is imparted to the yarn being wound upon the spindle 6 by theaction of centrifugal force uponthe guide and by the friction betweenthe latter and the lower face of the ring cover 9.

It will be seen that on the cop being complete d and the ring raillowered there is 7 nothing to-catch the outer windings of the completedcop as the guide is cylindrical and has no projections whatever. V v

The weight of the guide and the effect of its frictional contact withthe lower face'of the ring cover will be calculated as usual accordingto the counts of. yarns being dealt with. 1

I make no claim tothe use of the guide 7 as a traveller for use inspinning or doubling in the known way where the roving or yarn to bedoubled descends'direct from the front rollers to a traveller, as I findthat in using it in this manner there is a difiiculty at thecommencement of the cop winding and also in the winding of the yarnsat'the cop nose.'
